Integer Modes - 3: Bitwise Operations - HP RPN SCIENTIFIC WP 34S Owner's Manual

Integer Modes – 3:
Your WP 34S carries all the bitwise operations you may know from the vintage HP-16C,
plus some more. Generally, bits are counted from right to left, starting with number 0 for
the least significant bit. This is important for specifying bit numbers in the operations BC?,
BS?, CB, FB, and SB.
The following examples deal with 8-
set WSIZE 8, LZON on your WP 34S. For seven functions, you will find the schematic
pictures in the table below as they are printed on the backplate of the HP-16C. The 'C' in a
box stands for the carry bit there.
